Fluorocarbonates from biotite granodiorite, Slavkovský les Mts., Czech Republic
Original language description
Biotite granodiorites belonging to the redwitzite suite of western part of the Bohemian Massif occur as small bodies in metasediments of the Horní Slavkov crystalline unit and/or as inclusions in biotite granites of the Krušné Hory/Erzgebirge Mts. batholith. Biotite granodiorites contain plagioclase, K-feldspar, biotite, quartz, and accessory minerals (apatite, zircon). Some of these granodiorites were hydrothermally altered and during breakdown of biotite originated chlorite, titanite, ilmenite, and REE-fluorocarbonates. The anhedral grains and irregular aggregates of REE-fluorocarbonates appear homogenous in composition in back-scattered electron images. However, the detailed microprobe analyses of individual REE-fluorocarbonate grains show relatively high compositional variability on thin section scale, particularly with respect to their contents of Ca and Y. The REE-fluorocarbonates are represented by parisite, bastnäsite and relatively rare synchysite. REE-fluorocarbonates are more widespread in the Variscan granites of the Krušné Hory/Erzgebirge Mts. and Slavkovský les Mts. than previously considered. The occurrence of these REE-fluorocarbonates demonstrates that during later post-magmatic alterations, primary accessory minerals (allanite, monazite, xenotime, zircon) became unstable with remobilization of REE, Th, and U into newly formed secondary minerals (REE-fluorocarbonates and coffinite).
